Proxxon Micro-CombiSpeeder with joint

The 72-tooth inner ring made of high-alloy special steel allows for drive engagement with just a lever movement of 5 degrees. Nevertheless, the transferable torque values far exceed DIN/ISO standards. The shafts are made of CrV steel with optimal surface protection: nickel-plated twice and matte chrome-plated once. Clearly legible sizes are achieved through a laser marking process. The self-locking feature of the joint, which is very pleasant for practical work, remains unaffected even after more than 10,000 operations. Its unmatched flexibility makes it ideal for tight and tricky situations.
